The only reason I don't want two franchise tackles on this team is because it would cost too much money. But we have an opportunity to have two franchise tackles on our team at a very reasonable cost. Duane Brown's contract, while hefty, is pretty Texans friendly for a franchise LT. If we take a tackle with the #1 overall, he'll probably get a deal similar to what Eric Fisher got.

If there is a benefit to finding a QB to play at a high level, but low cost, surely there is benefit from getting the play of two LTs at the cost of one, $13M/yr.

It would be like having Jj Watt & JaDaveon Clowney in the same defensive front 7, only better.

Clowney and Watt might very well have equivalent value in the front 7, but the LT is always gonna be more valuable and more critical to the team than the RT, so that's an apples to oranges analogy.
But for whatever reason thunderkyss, I think I'm now resigned to the fact that you've got franchise LT on your brain and will leave it at that. For now.
